The pump truck A4 is composed of a pump wheel A4-1, a front fixing bolt 4-2, a pump truck frame A4-3, a wheel support plate A4-4 and a pin A4-5, and the pump truck frame A4-3 is a circle. Ring structure, its inner diameter is 0.5-1mm larger than the outer diameter of the water inlet of the submersible pump 6, the pump frame A4-3 is made with a wheel support plate A4-4, and the wheel support plate A4-4 passes through the pin A4-5 A pump wheel A4-1 is installed, the pump wheel A4-1 can slide along the inner wall of the pipeline 3 in the pipeline 3, and the front fixing bolts 4- 2. The front fixing bolts 4-2 are used to fasten the pump truck A4 on the submersible water pump 6. The pump truck B5 is composed of a pump wheel B5-1, a rear fixing bolt 5-2, a pump truck frame B5-3, a wheel support plate B5-4 and a pin shaft B5-5, and the pump truck frame B5-3 is a circle.

Because the pipeline 3 has good strength, the inclined type internal pump ecological water intake device can be cantilevered and extended into the water for a certain distance, so there is no need to build a cofferdam, the construction is relatively simple, and the construction process will not damage the original ecological waters . Since the motor of the water intake device is installed inside, the submersible motor 7 and the submersible water pump 6 are both arranged in the pipeline 3, which reduces the height of the water pump and the motor, which is 1-1.5 meters lower than the installation height of the existing water pump and motor. This enables normal water intake even in shallow water. Since the water intake of the water pump is lowered by 1-1.5 meters, compared with the existing similar design schemes using pipe-rail integration, the cantilever length of the pipeline 3 can be reduced by 2.5-4 meters, that is, if the pipeline needs to be cantilevered in the existing design scheme 5-8 meters, the cantilever length of the pipeline in the application scheme is only 2-3 meters, so under the same engineering environment and water intake conditions, the cantilever length of the pipeline 3 is reduced by 2.5-4 meters, and the cable-stayed technology is not required. , The construction is not affected by the season, it can be constructed all year round, and the project cycle is short, which can save a lot of project funds.

On the other hand, because there is no external cable, it can prevent the loss of cables, wire ropes and other materials, which solves the inconvenience of maintenance of the pump truck unit in the existing irrigation and drainage station, and the construction of cofferdams and external motors. problem, to meet the needs of water conservancy irrigation.
